FiTech EFI system

As far as I know the Mopar factory ignition doesn't work with the FiTech. The FiTech system will control the ignition without using any ignition box. You just run the blue wire to the negative side of the coil.
I’m helping a friend to make his engine run with a fitech system. Bought an msd pro billet dist including an adjustable rotor. No go, had it setup per instruction.
Not a sign to run.
Replaced the dist to a mopar orange box and not have the ignition controlled by fitech.
From the orange box there’s a wire to the negative post on the coil and likewise the blue wire from the throotlebody. Is this accurate?
Many thanks in advance.
